Product details
Overview
1N5360AE3/TR13 from Microsemi is a 5 W axial-leaded Zener diode with nominal regulation voltage of 25 V, ±10% tolerance (A suffix), 50 mA test current, 4.0 Ω maximum dynamic impedance at IZT, and 110 mA maximum Zener current (IZM) when adequately heat-sunk. It regulates voltage across industrial power supplies and voltage reference circuits operating from −65 °C to +150 °C.
For engineers reviewing the 1N5360AE3/TR13 datasheet, 1N5360AE3/TR13 pinout, 1N5360AE3/TR13 application, or 1N5360AE3/TR13 equivalent, key selection factors include its 25 V Zener voltage, ±10% tolerance, 5 W steady-state power rating at TL < 25 °C, low 25 °C/W junction-to-lead thermal resistance, and RoHS-compliant matte-tin plating.
Technical Context
This device operates as a reverse-biased voltage reference, maintaining stable output voltage under varying load and temperature conditions. Its regulation performance is defined by ΔVZ ≤ 0.55 V (voltage change between 10% and 50% of IZM) and ZZK ≤ 400 Ω at 1.0 mA knee current.
The 1N5360AE3/TR13 uses a void-free thermosetting epoxy T-18 package with cathode band polarity marking and meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity-no dry pack required. It withstands 8.3 ms half-sine surge currents up to 110 A and exhibits ESD insensitivity per MIL-STD-750 Method 1020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 25 V ±10% - defines nominal regulation point for precision reference design |
| Test Current (IZT) | 50 mA - operating point at which VZ and dynamic impedance are specified |
| Dynamic Impedance (ZZ) | 4.0 Ω max at IZT - determines voltage deviation under load current variation |
| Max Zener Current (IZM) | 110 mA - maximum continuous DC current before thermal runaway at TL < 25 °C |
| Power Dissipation | 5.0 W at TL < 25 °C (3/8″ lead length) - sets minimum heatsinking requirement |
| Thermal Resistance | 25 °C/W junction-to-lead - enables thermal modeling for PCB layout and heatsink sizing |
| Reverse Leakage (IR) | 0.5 µA max at 20.1 V - ensures low quiescent current in high-impedance bias networks |
Pinout & Package
Package: T-18 axial-leaded plastic encapsulated case per JEDEC DO-204AL. Cathode identified by single black band; banded end must be held positive relative to anode during regulation operation.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5360B | ±5% tolerance (B suffix) vs. ±10% (A suffix); otherwise identical electrical specs and package | Higher initial accuracy required for tighter reference designs; same thermal and surge ratings | Select 1N5360B when reference stability demands tighter initial VZ tolerance |
| MMBZ5255BLT1G | Surface-mount SOT-23 package; 25 V ±5%; 0.225 W power rating; 30 Ω ZZ | Low-power, space-constrained PCBs where 5 W dissipation is unnecessary | Choose MMBZ5255BLT1G only for signal-level biasing-not for 5 W regulation loads |
Compared with 1N5360B and MMBZ5255BLT1G, the 1N5360AE3/TR13 uniquely balances high-power capability (5 W), axial-leaded mechanical robustness, and RoHS compliance-making it optimal for industrial power rails where thermal margin and serviceability matter more than footprint size.

FAQ
What is the Zener voltage tolerance of the 1N5360AE3/TR13?
The 1N5360AE3/TR13 has a Zener voltage tolerance of ±10%, indicated by the "A" suffix in its part number. This means its measured VZ falls between 22.5 V and 27.5 V at 50 mA test current and 25 °C lead temperature. The tolerance is guaranteed per JEDEC specification and applies across the full operating temperature range of −65 °C to +150 °C.
Can the 1N5360AE3/TR13 be used without a heatsink?
The 1N5360AE3/TR13 can operate at full 5 W dissipation only when lead temperature (TL) is maintained below 25 °C-typically requiring a heatsink or substantial copper pour. At ambient temperature (TA) = 25 °C on FR4 with 4 mm² copper pads, its steady-state power drops to 1.47 W. For reliable 5 W operation, use 3/8″ (10 mm) lead length from body and ensure adequate airflow or metal chassis contact.
What does the "e3" and "TR13" suffix mean in 1N5360AE3/TR13?
The "e3" suffix indicates RoHS-compliant matte-tin plating per JEDEC J-STD-609, while "TR13" denotes tape-and-reel packaging per EIA-296 standard with 13-inch reels. Together, they specify a lead-free, automated-assembly-ready version of the 1N5360AE3/TR13 with industry-standard reel dimensions and orientation for pick-and-place equipment.
How does the 1N5360AE3/TR13 handle surge events?
The 1N5360AE3/TR13 is rated for a non-repetitive peak surge current (IZSM) of 110 A for an 8.3 ms half-sine waveform. This capability allows it to absorb transient energy in industrial environments-such as relay coil flyback or lightning-induced surges-without parametric shift or failure, provided the average power remains within 5 W limits and thermal mass prevents junction overheating.
Is the 1N5360AE3/TR13 suitable for precision voltage reference designs?
The 1N5360AE3/TR13 provides functional voltage reference capability but is not optimized for high-precision applications. Its ±10% initial tolerance, 0.55 V regulation delta (ΔVZ), and 4.0 Ω dynamic impedance make it appropriate for general-purpose regulation-not sub-0.1% metrology-grade references. For precision use, consider trimming with external resistors or selecting a ±1% (D suffix) variant like 1N5360DE3/TR13.
